alligator population by state

Louisiana What States have alligators? Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. [132] According to the Florida Department of Agriculture and Consumer Services, raw alligator meat contains roughly 200 Calories (840 kJ) per 3-oz (85-g) portion, of which 27 Calories (130 kJ) come from fat. [58], Alligators are raised commercially for their meat and their skin, which when tanned is used for the manufacture of luggage, handbags, shoes, belts, and other leather items. [23] Studies have found that eggs hatched at a temperature below 88.7F or a temperature above 94.1F will produce female offspring, while those at a temperature between 90.5F to 92.3F will produce male offspring. Females are produced at temperatures less than 31.5oC; mixed sex ratios occur at 32oC, and males only are produced when temperatures are between 32.5 and 33oC. Journal of Zoology, 260(3), 317-327. The same google search "How many alligators live in Florida" gave me this result With an estimated 1.3 million alligators in Florida, the state's Fish and Wildlife Conservation Commission is warning [26] Farther west, in Louisiana, heavy grazing by coypu and muskrat are causing severe damage to coastal wetlands. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. Visitors may take swamp tours, in which alligators are a feature. In Florida, feeding wild alligators at any time is illegal. (2016, April 30). Alligators, unlike the large crocodiles, do not immediately regard a human upon encounter as prey, but may still attack in self-defense if provoked. States began monitoring their American alligator populations to ensure that they would continue to grow. Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: A trophic cascade perspective on coastal wetland losses. [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. 1998. [32], Most of the muscle in an alligator's jaw evolved to bite and grip prey. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. In April and May, alligators form so-called "bellowing choruses". The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone. Southern Florida is the only place where both alligators and crocodiles live side by side. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). These states produce a combined annual total of some 45,000 alligator hides. Wetland Ecology: Principles and Conservation (2nd edition). In order to understand and properly manage Texas's alligator population, TPWD Wildlife Division conducts extensive studies in the state on the number, character and harvest of alligators every year. While events of predation by Burmese pythons on any sizable American alligators have been observed,[94][119][120] no evidence of a net negative effect has been seen on overall American alligator populations. Since hunting and trapping preferentially take the large American alligators that are the most important in eating nutria, some changes in harvesting may be needed to capitalize on their ability to control nutria. Large groups of animals bellow together for a few minutes a few times a day, usually one to three hours after sunrise. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. [48] Some American alligators are missing or have an inhibited gene for melanin, which makes them albino. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink.

Florida has a population of 1.3 million alligators across its 67 counties, and they can be found in practically all fresh water bodies and occasionally in salt water. The state has one million wild alligators and another million on alligator farms. Alligator feeding habits: New data and a review. The natural sex ratio at hatching is five females to one male. -23.28% (-27) Rank in State 354th Rank in Country 26937th The current population of Alligator, Mississippi is 89 based on our projections of the latest US Census estimates.The last official US Census in 2020 recorded the population at 116. (2010). During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. She will provide protection to the young for about a year if they remain in the area. Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. The American Alligator population was dramatically reduced by the 1950s and 1960s and a majority of the wild population was likely lost (USFWS 2008). [50] Juveniles have small, needle-like teeth that become much more robust and narrow snouts that become broader as the individuals develop. [90][91] Although American alligators have been listed as predators of the Nilgai and the West Indian manatees, very little evidence exists of such predation. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. [29][30][31], Although the alligator has a heavy body and a slow metabolism, it is capable of short bursts of speed, especially in very short lunges. [12], No average lifespan for an alligator has been measured. [4][5] The Chinese alligator split from the American alligator about 33 million years ago[4] and probably descended from a lineage that crossed the Bering land bridge during the Neogene. [44] Most other amniotes are believed to exhibit bidirectional, or tidal breathing. [41] The mother defends the nest from predators and assists the hatchlings to water. [2] Later English spellings of the name included allagarta and alagarto. "Gators" has been the nickname of the University of Florida's sports teams since 1911. The fundamental frequency has been influenced by the glottal gap size and subglottal pressure and when the phonation threshold pressure has been exceeded, there will be vocal fold vibration.[107]. Watch on. Only one of the American alligators was collected from the Colorado River, Mesa County, Colorado; the other was never recaptured, but there is no evidence of an established population (Livo et al., 1998). [50] American alligators have broad snouts, especially in captive individuals. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. [64], American alligators are listed under Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning that international trade in the species (including parts and derivatives) is regulated. Once an American alligator reaches full size and power in adulthood, any animal living in the water or coming to the water to drink is potential prey. TPWD issues the tags, required by state and federal law, based on the alligator population on the privately owned tract. [37][27] As humans encroach into their habitat, attacks are few but not unknown. [77] This means they are among the first reptiles recorded to use tools. The Mississippi Department of Wildlife, Fisheries and Parks (MDWFP) runs an annual alligator survey along approximately 317 miles of waterways on 15 routes in 13 counties. [89] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. Most of the state gets much too cold for gators to survive the winter, but there are some small regions that allow for a small population. Like many reptiles, alligators reach a larger size in Florida and other southern latitudes, sometimes reaching 15 feet. [45], The alligator has a similar digestive system to that of the crocodile, with minor differences in morphology and enzyme activity. The 11 feet-long gator was later captured and killed. As human populations increase, and as they build houses in low-lying areas, or fish or hunt near water, incidents are inevitable where humans live near American alligators and their habitats. [46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. The below cladogram shows the phylogeny of alligators. They can grow to be more than 12 feet (3.6 meters) in length and weigh as much as 1,000 pounds (450 kilograms), with males being slightly larger than females on average. This doesn't mean that residents should expect to see an alligator hanging out on every corner, but they shouldn't necessarily be shocked to spot an Alligator now and again either. [16], The alligator's full mitochondrial genome was sequenced in the 1990s, and it suggests the animal evolved at a rate similar to mammals and greater than birds and most cold-blooded vertebrates. [17] However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.[18]. It is one of the two extant species in the genus Alligator, and is larger than the only other living alligator species, the Chinese alligator . [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. [70] In fact, the American alligator is found farther from the equator and is more equipped to handle cooler conditions than any other crocodilian. The two kinds of white alligators are albino and leucistic. In NC, males can reach 13 feet and weigh up to 500 pounds or more. [108] The American alligator can perform specific vocalizations to declare territory, signal distress, threaten competitors, and locate suitable mates. Biologists recently estimated that the state has between 32,000 and 38,000 alligators, far fewer than either Florida or Louisiana. [22], Additionally, American alligators have recently been filmed and documented killing and eating sharks and rays; four incidents documented indicated that bonnetheads, lemon sharks, Atlantic stingrays, and nurse sharks are components of the animal's diet. may seem too good to be true, but then, some truths are quite incredible in themselves. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. Florida . The acidity of the stomach has been observed to increase once digestion begins. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. The American alligator was abundant in the pre-drainage Everglades in south Florida. Oxygen exchange takes place in extensive vasculature around the parabronchi. The baby alligator's egg tooth helps it get out of its egg during hatching time. The American alligator is a stunning example of a species that has fully recovered in large part due to protections provided by the Endangered Species Act. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. The Amphibians and Reptiles of Louisiana. [24] A few examples of animals consumed are largemouth bass, spotted gar, freshwater pearl mussels, American green tree frogs, yellow mud turtles, cottonmouths, common moorhens, and feral wild boars. This process makes digestion and nutrient absorption easier once the food reaches the second portion of the stomach. Captured alive by John Avery and died en route to the Smithsonian Institution after a sailor poured green paint on its back. [7], The genus Alligator belongs to the subfamily Alligatorinae, which is the sister taxon to Caimaninae (the caimans). It has more alligators than any other state. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. In mature males, most specimens grow up to about 3.4m (11ft 2in) in length, and weigh up to 360kg (790lb),[7] while in females, the mature size is normally around 2.6m (8ft 6in), with a body weight up to 91kg (201lb). Fish and Wildlife Service pronounced the American alligator fully recovered. The wild population of Mexican wolves in the United States continued to grow in 2022. They play an important role as ecosystem engineers in wetland ecosystems through the creation of alligator holes, which provide both wet and dry habitats for other organisms. Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. The sex of the offspring is determined by the temperature in the nest and is fixed within seven to 21 days of the start of incubation. Description American alligators are large crocodilians found only in the United States. In 1967, the American alligator was listed as an endangered species (under a law that was the precursor Endangered Species Act of 1973), since it was believed to be in danger of extinction throughout all or a significant portion of its range. However, they can not walk on their hind legs. The Florida Naturalist, 41, 27, 6974. and early 1960's, but protective action by state and federal governments helped keep them from disappearing completely. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. [80][81], American alligators are considered an apex predator throughout their range. This type of protection allowed the alligator population to increase. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. Similar to many other reptiles that range expansively into temperate zones, American alligators from the northern end of their range, such as southern Arkansas, Alabama, and northern North Carolina, tend to reach smaller sizes. Louisiana and Florida. [10] It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical and warm subtropical climates. [74] In the limestone depressions of cypress swamps, alligator holes tend to be large and deep, while those in marl prairies and rocky glades are usually small and shallow, and those in peat depressions of ridge and slough wetlands are more variable. Louisiana has the largest alligator population. 911 Call Reveals Moments After Gator Attacks Elderly Woman. The discovery of this unexpected part of the American alligator diet further reveals that they may be responsible for spreading seeds from the fruit they consume across their habitat. [24] When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. [88], Other animals may occasionally be eaten, even large deer or feral wild boars, but these are not normally part of the diet. In 1987, the U.S. Wild Alligator Harvest Summaries By Year 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 This listing provides federal protection for alligators but allows state-approved management and control programs. An alligator, or just gator, is a large reptile in the Crocodilia order in the genus Alligator of the family Alligatoridae. They may kill larger prey by grabbing it and dragging it into the water to drown. [19] Weight varies considerably depending on length, age, health, season, and available food sources. [76], American alligators have been documented using lures to hunt prey such as birds. The American alligator (Alligator mississippiensis), sometimes referred to colloquially as a gator or common alligator, is a large crocodilian reptile native to the Southeastern United States. For example, one long-term mark-recapture study (1979-2015) done at the Tom Yawkey Wildlife Center in South Carolina found evidence to support patterns of determinate growth, with growth ceasing upon reaching a certain age (43 years for males and 31 years for females).
